This invention deals with mine 'cars in general and in particular withmine cars ofthe stubaxle type for rotary dumping.

of this invention to provide a wall and outer axle bearing memberconnected by a strong box-section.

A still further object of the inventionfis the provision of a stub-axlemine car having the inner bearing members connected by a tubular bracingmember.

These and other objects of the invention will lbe apparent to oneskilled in the art from a study ci the following drawings, in whichFigure l is a side view of substantially onehalf of the car, parts beingbroken away to more hood;

Fig. 2 is a side view of the other half of the car with the bumper beingshown in section;

Fig. 3 is an inverted plan view of the car, portions thereof beingomitted;

Fig. 4 is an end view of slightly more than half of the car, and

Fig. 5 is a sectional view taken on line 5-5 of Fig. 3.

Referring now to the drawings invr detail, the car is shown as of therotary dump type with fixed ends but it is obvious that it is equallyWell adapted for end dumping by the mere provision of an enddoorlandpossibly braces atthe open end. The inner or side sills are ofangle form having a vertical web 2 projecting into-the lading Zone andan inturned bottom flange 4. The ends of the sills overlap andare'connected to the sides 6 of the cast end members which aresubstantially of channel form bracedxby the inclined portions 8. One endmemberis provided with a combined spring buffer and draft gear A, whilethe other member is provided with arigid draw element B and woodcushioned bumper cap C.

Each end member is provided with projecting anges l0 to which is rivetedthe end Wall l2 having its ends extending inwardly atan angle forconnection to the plate girder side walls I4.

wardly directed flange I 8 of a bottom chord of angular formation. Asshown more clearly in Fig. 5, the bottom chord of the plate girder issection, though this, obviously, is merely by way of example. Theinturned lower ange 20 of the chord forms a supbeing disposed mwardlyfrom the plane of the side wall insures complete clearing of the carwhen turned upside down in the dumper. The upper end portions of theside walls have 35 one piece but in any case will be attached to, and

supported by, the Various iianges referred toA previously.

The wheel hoods and cross support members are shown as pressed in onepiece with side iianges 4S, upstanding walls 48, top Wall or coverportion 5D which connects the side walls, and

K wall 52, dome-shaped hood portion 54, and outer 55 The innerupstanding central portion 64 2 hood and cross support memberspreferably have the bearing brackets connected thereto and properlyaligned prior to attachment to the car and their attachment to the caris accomplished by securing the flanges 46 to the car floor, the endwall and inner bearing bracket to the sill flanges, the outer end an-gesto the girder side walls and the outer bearing bracket flange to thefloor sheet. It will be seen that the combined hood and support member,together with the girder walls and floor sheet, forms a full box sectiono1 great strength extending between the outer bearing member and sidewall. The load on the car floor will be transmitted to the axles andwheels by the inner sills and by the box section Ysupport members, whichlatter receive the load from the girder side walls.

Braces 10 of inverted U form have flanges 12 securedV to the floor sheetand these braces extend between the inner sill members substantially inalignment with the axles. The brace' ends are flared upwardly as at 14and provided with end flanges 16 to receive rivets securing the brace tothe sill and also with upwardly directed ange 'I8 which secures togetherthe brace, wheel hood and central extension 64 of the inner bearingbracket.

The various parts and construction of the car have been described indetail but it is obvious that changes may be made such as forming thesupport member as a pan-shaped pressing to which would be welded thedome-shaped wheel hood proper, or the pressing could be made in twoparts welded together and these changes as well as others arecontemplated which fall within the scope of the appended claims.

What is claimed is:

l. In a mine or similar car, girder side walls, sill members, combinedwheel hood and support means connecting said sill members and girderside walls, a floor supported by said means and by said side walls andsill members, inner bearing brackets secured to said sill members, outerbearing brackets secured to said support means in spaced relation tosaid sills and side walls, said support means being substantially ofclosed box-section between said outer bracket and side wall.

2. In a mine or similar car, the combination of plate girder side wallshaving top and bottom chords, sill members spaced from said walls,combined wheel hood and support units connecting said sill members andplate girder side walls, a floor supported by said units and by saidplate girder side walls and sill members, said floor extending under thewheel hood units and having Wheel receiving openings formed therein,inner bearing brackets connected to said sill members,

outer bearing brackets secured Within said support means intermediatethe girder side Wall and adjacent sill member, said outer bearingbrackets being also directly connected to the floor, and wheel supportedaxles extending between said brackets.

3. A combined wheel hood and support unit for mine and similar carscomprising, a unitary metal pressing having, upstanding side walls, aninner end wall, and a cover portion connecting said walls, said coverportion having a part thereof located in a substantially horizontalplane and a part thereof pressed upwardly to form a wheel hood.

4. A combined wheel hood and support unit for mine and similar carscomprising, a unitary metal pressing having, upstanding side walls,laterally directed flanges at the lower edge of the side Walls, endwalls, and a cover portion connecting -said walls, said cover portionhaving a part thereof located in a substantially horizontal plane and apart thereof pressed upwardly to form a a wheel hood.

5. In a mine or similar car, the combination of side walls each having atop chord and a bottom chord of angular formation including a horizontalportion and a depending portion arranged inwardly with respect to thewall, sill members spaced from said Walls, combined wheel hood andsupport units connecting said sills and side walls, a floor supported bysaid units and by said side walls and sill members,` inner bearingbrackets connected, to said sill members, outer bearing brackets securedto said support units intermediate the side wall and the adjacent sillmember, and wheel supported axles arranged in said brackets, said angleshaped bottom chords forming recesses for the reception of car haulstops.

6. In a mine or similar car, a side wall having top and bottom chords,thelatter being substantially Z shaped in cross section with theflangesI thereof horizontally arranged whereby to provide a recess forthe reception of a car haul stop, a sill spaced from said wall, acombined wheel hood and support unit connecting said sill and side wall,a floor supported by said unit and by said side wall and sill member, aninner axle bearing secured to the sill, an outer axle bearing arrangedwithin and secured to said support unit between the side wall and sill,and a wheel supported axle arranged in said bearing.

7. In a mine or similar car, girder side walls, sill members, combinedWheel hood and support units connecting said sill members and girderside walls, a substantially single level floor supported by said unitsand by said side walls and sill members, said floor extending under thewheel hood units and having wheel receiving openings formed therein,inner bearing brackets secured to said sill members, outer bearingbrackets secured within said support means in spaced relation to saidsills and side Walls, said outer bearing brackets being also directlyconnected to the floor, and wheel supported axles extending between saidbrackets.

8. In aV mine or similar car, girder side walls, sill members, combinedwheel hood and support units connecting said sill members and girderside Walls, a door supported by said units and by said side walls andsill members, said floor ex` tending under the wheel hood units andhaving Wheel receiving openings formed therein, inner bearing bracketssecured to said sill members, outer bearing brackets arranged within andse cured-to said support means in spaced relation to said sills and sideWalls, said outer bearing brackets being secured to the floor, wheelsupported stub axles extending between said brackets, and meansconnecting said sills and units and located substantially in alignmentwith said stub axles.
